MARYLAND VEGETABLE PLANT SPRAYER Application filed February 27, 1931. Serial No. 518,680.

This invention relates to a powder dispensing and spreading device and has special reference to an insecticide dispenser for powdering plants and other objects.

: One important object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide a device of this character having improved means for delivering successive portions of powder to a delivery nozzle carried by the device.

A third important object of the invention is to provide a bellows for such a device so connected to the powder delivering means that the operation of the bellows effects operation of such means.

A fourth important object of the invention is to improve the arrangement of the several parts of the device so that they mutually support each other.

With the above and other objects in viewas will be hereinafter apparent, the invention consists in general of certain novel details 5 of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a side elevation of the invention.

Figure 2 is a front elevation thereof.

Figure 3 is a section on the line 33 of Figure 1. I

Figure 4 is an enlarged detail section on the line 4-4 of Figure 3.

As here shown the invention includes a bellows 10 having a relatively fixed back board 11 and the relatively movable front board 12 hingedly connected to the back board by the leather of the bellows in the.

common manner. A handle 18 on the back 5 board serves to form supporting means for the entire device while a handle 14; on the front board forms means for working the bellows. Extending downwardly from the nose of the bellows is a tube 15 which ispro 0 vided with a right angled bend 16 so that the portion of the tube remote from the bellows extends horizontally as at 17. A powder receptacle 18 has its upper part fixed to the back board 11 and has a bottom 19 of inverted pyramidal shape resting on and opening into the tube portion 17 The receptacle is provided with a suitable hinged lid or cover A rock arm 25 is fixed on a projecting end of the shaft 23 and is connected by a link 26 with one arm of a bell crank lever 27 pivoted at its angle to the side of the back board 11. The other arm of this bell crank lever is connected by a link 28 to a pin or stud 29 on the side of the front board 12.

Detachably and rotatably mounted on the forward end of the tube portion 17 is a delivery nozzle 30.

By means of this arrangement operation of the bellows efiiects operation of the valve, the valve, which also forms an agitator, opening each time the bellows is opened to draw in air and closing each time the bellows is closed to expel air. Thus successive portions or charges of powder are fed into the tube 17 before the nozzle 22 and are blown out of the delivery nozzle 30 by the action of the air flowing from the smaller end of the nozzle 22.

There has thus been provided a simple and efiicient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing fromthe ma terial spirit thereof. It is not, therefore, de sired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

In a device of the kind described, a bellows including a vertical back board and a front board connected to the back board for oscillation about an aXis adjacent the lower end of the back board, a powder receptacle having its upper end fixed to the lower end of the back board and extending downwardly from said back board, said receptacle having a delivery opening at its lower end, a valve in said opening controlling the flow of material therefrom and having a journal end projecting exteriorly of the receptacle, a bell crank pivoted at its angle and supported from the edge of the back board, a link pivoted to the front board and connected to one arm of the bell crank, a rock arm fixed on the projecting journal, and a second link connecting the remaining arm of the bell crank and said rock arm.

In testimony whereof we affix our signatures.
